In this letter, two types of substrate-integrated defected ground structure (SIDGS) resonators (i.e., loaded-stub and C-shape resonators) are proposed for the ultra-wideband (UWB) bandpass filter (BPF) design. Coupled SIDGS can generate four transmission poles to achieve UWB response with low insertion loss in a compact size. Besides, spurious cancellation broad stopband is achieved by mutual s...

This examination work is focused around planning and simulating another kind of inset feed Disc Shaped Microstrip Patch Antenna (DSMPA) with Inset Defected ground plane (DGP). By presenting a round space at the focal point plane, improved attributes patch antenna can be accomplished. The proposed reverberating 5 GHz. Simulation has been finished by utilizing reenactment programming HFSS version...

Design of a compact broadband filter using tightly coupled line sections in defected (A slot is cut in the ground) microstrip medium operating from 3.1–6.8 GHz has been reported in this article. Filter has been designed and analyzed using an equivalent circuit model based on even and odd mode parameters of coupled line sections. The proposed filter has attenuation poles on either side of the pa...

A novel compact triple elliptical monopole antenna has been designed, analyzed and fabricated for super wideband applications. To enhance the impedance bandwidth, author proposed a with patch excited by 50Ω triangular tapered microstrip feedline. Further improvement is achieved optimally modifying Defected Ground Structure (DGS) of antenna. The structure mounted on Roger’s RT-Duro...

Linear tapered slot antennas (LTSAs) have been widely investigated as typical examples of coplanar antennas because the LTSAs offer the advantages of wide impedance bandwidth, high gain, and easy fabrication [1], [2]. However, they have high back lobes in the E-plane [3]. In general, the LTSAs are very sensitive to the thickness and the width of their supporting substrate. It is shown that radi...

This article presents the design and characterization of a dual-band, compact, dual-circularly polarized (CP) traveling wave series-fed circular slit microstrip array (TWSCSMA) antenna operating in quad-band CP at 2.5/3.5/3.8 GHz WiMAX 5.2 WLAN applications. The radiating structure consists an annular ring elements, rotates sequence with seven quasi-lumped resonators contributes to two-impedanc...
